I'm using a Ryzen5 3400G (no external video card) with a Gigabyte B450M-DS3H motherboard. My video monitor is a Samsung SyncMaster T220, conected with HDMI (motherboard side) - DVI (monitor side) cable.
What happens is that, sometimes (4 times in one month), the video is lost and the screen shows only a noise video, something like a TV station without signal. I attached a picture of the screen.
The video returns when I re-connect the cable. It seems that some signal is reseted.
Has anybody seen this kind of issue? Thanks
